' OIL-BURNER xMANN, a citizen of the United States, a

resident of Dixon, county of Solano, State of California, have in nted a new -and ln1- gines generally,; is more particularly.,.de-

. signedflfor embodiment in theburners of traction engines; pulling. combination har- 'vesters.

The danger fire the harvest f field is very great with ordinary. types ;of burn. ers, owing to-the ejection of sparks due to'the deposit of carbon inthe smoke stack.

Objects of my invention are to provide a.

burner in the. use, of which carbon deposits thereby obviating the clogging of the burner and the danger from fire causedby 'sparksz' to provide a burner of the gravityfeed typeemploying a steam jet to produce a'fuel mixture in the form of a spray and insure a steady discharge of the fuel mixture with out preheating of the crude oil to. a high degree and the liability of the fuel column being forced'back in the feed pipe; to provide a burner that may be so arranged at the front of the furnace, as to direct a spray of fuel and steam upwardly to the fire box, thereby to effect a thorough mixing of the fuel and steam in the fire box; to provide an oil burner free from the danger of' back fire; to provide for the discharge of the fuel I in a steady and equalized stream; and to provide a burner of simple construction, easilyadjusted and applied.

The special character of my improved burner and its distinctive features will appear from the specific description following. Reference is had to the accompanying drawings forming part of this specification,

in which similar characters of reference indicate corresponding parts in all the views,

and in which:

Figure 1 is a side elevation of my improved-burner showing the same mounted for use; Fig. 2 is a'longitudinal vertical .sec-

tion of the burner on a large scale; Fig. 3 is a fragmentary view showing in perspective the nozzle of the burner body, or the shell; and Fig. 4 is a similar view of the steam nozzle.

In constructing a practical embodiment l of my. invention in accordante the ane arra ge-.1915.

tra ted example, the bodyof lthe burner contain liquid fuel, nd-has suitable means; at its rear end for stablishing connection with sists of an elonggad shell 10 adapted to conthe fuel supplyri In the illustrated form av head 11 has threadedfconnection with the" shell 10 and-fwith; a vertical oil-.pipe 12to be connected in practlee with any. elevated vided with a valve 13, pro valve, toeontrol thefuel feed.

= W1th1n.th ;e' fuelshell .10 is a longitudinally disposed zsteam tube '14 7 which extends through: ther'head 11 to .a steam'pipe 15 which communicateswith the steam space The sh 1-0. atits front endis' formed into of the boiler;atganygfconvenient point, as'at 16.; 1h e. steamtp pe-l5 is equipped with a controlhn areprevented in the'burner and Smokestack,

a nozzle, bein .flattened, and resentinga transverse,iob ong discharge ot..18.' .The slotzl8xis-directly beneath the .top

obliquely upward from the bottom of the shell,,the upper edge of the." frontwal1 19 steam tube -14 is formed to correspond with the nozzle and discharge slot of the fuel 10 nearer the top thereof than the-bottom,-

and the discharge slot 20 of the steam tube of the I shelllO; andbelow; the said slot the shell .10

1s formediwith a front 19 extending.

defining the bottom of the slot 18. The

is thus located inward 0F rearward from the slot 18 of the fuel shell and below the latter; The arrangement provides 'for an ample supplyof fuel at the front of the burner. between the walls '19 and 21 and immediately adjacent thereto with a body of oil maintained between the discharge slots of the steam nozzle and the fuel nozzle.

The invention is shown in connection with a boiler A of the locomotive type, and is disposed in an opening a at the front 'of the boiler leading to the fire box near the bottom. The form of the burner at the front as described causes a steam spray to be dipreheating of the fuel is required, and there-* and through the discharge slot 18' of the fuel shell and through the intervening body of crude oil between "the slots 18 and 20. llhe result is that a spray of combined steam and' fuelis directed upwardly into and through the fire box, and the fuel and steam will thoroughly mix in the fire box, so that an ample supply of fuel isdischarged in a' steady and equalized spray. The burner-is.

free from deposits of carbon, and the composition is such that no carbon will be deposited in the smoke stack with the resulting liability of danger from sparks; also, no

fore no back pressure is developed in the burner, with the liability of forcing back the fuel column in the gravity feed pipe.

Having thus described my invention, what ll claim as new and desire to secure by Letdischarge slot transversely disposed directly adjacent to the top of the shell, the said nozzle, below the slot, presenting a front wall inclining upwardly and forwardly from the tube and the said steam tube having a correspondingly formed flattened nozzle with an oblong discharge slot below and rearward of the slot of the fuel nozzle, the steam nozzle having an upwardly inclined front wall spaced from and substantially parallel with the inclined front of the fuel nozzle.

2. A fuel burner of the character de- Y scribed, comprising an elongated outer fuel shell having a flattened discharge nozzle at bottom of the shell and in front of the steam the front end presenting a transverse ob- I long'discharge slot directly adjacent to. the flattened top of the shell, a head having threaded connection with the rear end of the. shell and with a vertical oil supply pipe, and

an elongated tube disposed longitudinally "within the shell and extending at its rear end through the said head, said tube being provided with means at its rear end to connect with a fluid supply to be mixed with the fuel and having at its front end a nozzle presenting an oblong,ftransverse discharge slot in the rear of and below the discharge slot of the shell and adjacent to the top of the said tube. 7

ln testimony whereof if have signed my name to this specification in the presence of two subscribing witnesses.
